- IMPRQVEMENT IN ANCHORS.

The Schedule referred to these Letters Patent and makingpart of the sama To all whom it 'may concern Be it known that I, G. C. PATTISON, ofthe cityand county of Baltimore,V and State 'of Maryland, have improved Portable N onFoul ing Anchor; and I do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, in which- Y Figure l is a perspective view of my improved anchor complete.

Figure 2, plan w'ews, illustrating the several parts of the anchor detached. l

, Similar letters indicate like parts in all of the views.

My invention relates to an improvement in non-fouling pivotedai m anchors, to render the same portable and compact, to secure and guard the same more completely, when in use, against fouling ofthe ships chains and cables therewith; and

First, in constructing the anchor in three pieces, viz, a shank, A, stock B, and pivoted duke-arm C, so made and combined as to admit of being readily separated, and as readily united, to form a strong, secure anchor;

Second, in combining with the detachable stock and pivoted arm ofthe anchor, guard-chains, or rods,-ex tending from the extreme ends of the stock to the pivot--pin of the arm at the crown of the anchor, or toy the lower end vof the shank, at or near said pivot; and' Third, in combining stay-rods with the horns of the fluke-arm, to extend from the points thereof' to the extremities of -the dukes, to prevent a fouling of the latter. A

In the accompanying drawings-A v A represents the shank of my improved anchor.' Its upper end is provided with an ordinary shackle, or ring, for the attachment of the cable thereto, and is pierced with a suitable aperture, to receive the detach-- able stock B, and its lower end slotted, to receive a pivoted duke-arm, C.

The stock B, when inserted inthe shank A, -is secured thereto by a key-bolt, j, passing through a slot, c', in the stock, or in any other suitable manner, and it may be either' straight, or have its ends bent, as illustrated in the drawings.

The duke-arm O, of theanchor, made in a solid piece, entirely separate from the shank A, is centrallypivoted within the slot in the lower end of the shank, by means of a bolt, or pin, z, which may be threaded at one end, to receive and be secured by a nut, or slotted to receive and be secured by a wedge-shaped key, or otherwise secured, as may seem expedient.

The ends of the stock B are fitted with shackles, or detachable links b b, carrying chains, or loose rods E The lower ends of these chains terminate in eyes c c, made to slip into the pivot-pin z.

Horns D', of the ordinary description, as found in the government anchors, maybe formed upon .the outer face of the duke-arm C, at each end thereof', in the rear of the dukes, to insure the" tripping of the arm and an engagement of the duke with the bottom.

I combine, however, with these horns D', when used, guard-straps, extending from the ends of the horns to the points ofthe dukes, as illustrated inthe drawings, to prevent a foulingof the dukes by the chains or cables.

The straps also become serviceable in dshin g for the anchor when lost, as the drag-hook will readily catch and hold under the same. l

Projections E F are formed upon each side of the shank A, and recessed to receive the dukes D, when they swing up against the shank, so that when one of the dukes is buried in the bottom, the point of the upper duke, fitting into the recess of the projection F, is thereby so completely shielded as that the cables, or chains, cannot catch therein, and foul therewith.

These projections F F are also very useful, ,from the fact that they greatly strengthen the shank at its weakest point.

4 When not required for immediate use, my improved anchor may be stowed in the smallest possible compass, by removing the pivot-pin z, thus'releasing entirely the duke-arn C, and the ends of the guard-chains, or rods, E, from the shank A, and then detaehing thekey or other fastening securing the stock B to the shank, so that it may also be dra vn therefrom.

'The shank, stock, and duke-arm, being thus entirely separated, maybe laid together, and stowed side by side.

This ready detachment and separation of the several ,parts of the anchor is very serviceable in the transpor- -itation `Of heavy anchors, especially so when it becomes necessary to transfer them from one ship to another in a heavy sea, as each piece may be handled and carried independently ofthe others.

In ordinary use, instead of detaching the duke-arm C from the shank A, one of the chains E may be detached from the stock B, and the stock alone be withdrawn from the shank, so that the anchor may lie close upon deck. j

Having thus fully described my invention,`

'I claim as new, and desire to secure by Letters Patent- In combination with a detachable stock, B, detachable, pivoted duke-arm C, and shank A, of an anchor, constructed substantially as herein described, the detachable guard-chains, or rods, E E, extending from the extreme ends of the stock B to the lower end of the shank A, substantially in the manner and for the purpose herein set forth.

Also, the combination of guard-straps with the horns D and dukes D, of the duke-arm C, substantially in thev manner and for the purpose herein set forth.

'Ihe foregoing specification ofmy improvements in anchors signed by me, this 16th day of October, A. D.
